V nssa'seo.

To all whom it may concern:- 7 4 I Be it known that I, How BEIL, a citizen of the United States, residing in- Lawrence, in the county of Essex and State of'Massa ohusetts, have inventedan Improvement in Antiskid, Devices for Motor 4 Vehicles, .of which the following description, inconnection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

' This 'inventlon relates to-m0tor vehicles and particularly to automobiles of the pleasure type,- and has for its objectto provide means whereby skidding of the wheels may be prevented or at least reduced to a minimum.

To this end, one or more of the wheels has cooperating with it a chute or pipe leading from a receptacle carried by thevehicle and containingsand or like material.

" The'chute'or pipe'for'the best results is arranged with its outlet or. discharge end above a horizontal plane: through the'a'xis ofthe'wheel with which itco6peratesand also in front of a vertical plane through said axis, so astodischarge the sand upon the tire-or shoelof the" wheel and thereby coat the'latter more or less, and convert the smooth slippery surface of the tire or shoe into a roughened or gripping surface, which 7 when engaged with the slippery roadway will prevent skidding of the wheel or at least reduce skidding to such extent as to avoid accidents therefrom. Y 7

Provision is made for controlling the flow of sand to the wheel by the operator of the vehicle, as will be described.

The flow of sand is controlledby a valve which is self-cleaning as will be described.

'These and other features of this invention will be pointed out in the claim at the end of this specification.

Fi mobile embodying this invention. 'Fig. 2, a plan view of the sanding device for the rear wheels, the vehicle being shown in outline.

6 chutes or pipesc, havd 'ing their. outlet mouths located above a hori- In'the present instance,'each chute or pipe 7 c'communicates with a receptacle 13 carried A by the vehicle and designed. to contain sand or like gripping material. The 'fiow "of sand from the container or receptacle 13-is'conl,

trolled by a slide valve or plate 14, which is mounted to slide in a suitable casing, her in shown as composed of an upper member'15 and a lower member16, which latter is provided' with an offset portion 17 (see Fig. 4'),

to form a way in which the valve 1 1 slides.

'Thelow'erinember 16 has attached to it;

chute'or pipe 'c,'which leads laterally therefrom. The offset portion 17;: 1

the receptacle is facilitated by providing the verge toward the opening22. The slide also provided witlr'an opening- '21, which The opening 21 is normally closed. by i prevents escape of the sand valve 14 may be operatedin any suitable manner and is represented-as operated by a to the" vehicle a in position to'be worked by and said valve lever by a linker rod 25. The lever 24: is shown as located at the front ofthe vehicle and as one suitable for operation by hand,

but it may be such as to be operatedby the foot of the operator. In order that a single lever may simultaneously operate the valves A 1 1 controlling the flow of sand or like mate rial to the two rear wheels of the vehicle, the valves 14 and their casings are arranged so as to converge andenable their links or rods 25 to be connected with the single operating lever 24, but 1t lsnot desired to limit the invention to this particular arrangement.

By reference to Fig. 1, it will seen that 1 '1" the operator ofthevehicle," may be connected with said v or pipes a rear wheels is insured of the vehicle pulls the when the operator or n the direction of t lever 24 backward ne arrow 26, the links 25 and the valves lt are drawn forward, and the openings 20, 21, are uncovered, which allows the sand to flow by gravity from the receptacles 13 through the chutes or pipes 0 onto the surface of the tire or shoe of the motor vehicle, which under skidding conditions are more or less wet, and suflicient of the sand will adhere to the wet surface of the tire or shoe, to provide the latter with a suificiently roughened or gripping surface to prevent lateral or skidding movement of the wheels.

By locating the chutes or pipes, 0 so that their outlet mouths are in front of a vertical plane through the axis of each rear wheel, and above a horizontal plane through said axis, the sand is deposited on that portion of the tire or shoe about to be brought into contact with the ground, so that the gripping surface of the wheels formed by the sand or the like is brought into engagement with the slippery or wet roadway and becomes effec tive to grip the roadway substantially in an instant andbefore the wheels can start to skid.

' By locating the outlet mouth of the chutes above a horizontal plane t rough the axes of the wheels, the operative relation of the outlet mouths of the chutes to the both when the vehicle is light and also when heavily loaded.

In the presentinstance, anti-skid. devices are shown for both rear wheels, but if desired additional devices for the front wheels may be provided, 7 7

To facilitate operation of the valve 14; with a minimum effort and to render the valve self-clearing, the valve casing is open at its rear end as shown in Fig. 3, which enables the valve to push the sand in front of it out through the rear opening in the valve casing when the valve is being closed, which prevents clogging of the valve and loss of sand when the device is not being used.

In the present instance, one construction of mechanism is shown but it is not desired to limit the invention to the particular construction shown.

I have described the bodied in. a pleasure motor invention as em- Vehicle, but it is not desired to limit the invention in this respect, as it, is equally applicable to, commercial motor vehicles.

The combination with a motor vehicle provided with wheels, of a receptacle for sand or like material carried by said vehicle and provided with'an outlet pipehaving its outlet mouth arranged in front of a vertical" lane through the axis of a wheel of said vehicle and above a horizontal plane through said axis, a valve casing interposed vbetween said receptacle and said outlet pipe and open at its rear end, a valve slidable in said casing to. controlthe flow of material from the receptacle onto the circumference of said wheel, and means under control of the operator of said vehicle for operating said valve. 7

In testimony whereof, Ihave signed my name to this specification.
